Showcases precise, resilient timing capabilities of TerraPoiNT service for critical infrastructure applications
NextNav, the leader in next generation GPS, announced that it has successfully demonstrated the timing precision and resilience of its terrestrial Position, Navigation, and Timing (PNT) system, TerraPoiNT, in a recent evaluation by the Science & Technology Directorate (S&T) of the Department of Homeland Security (DHS). The trial, an industry-first, tested the timing redundancy of the TerraPoiNT system in a number of scenarios, including instances of GPS outages, spoofing, and jamming. It validates TerraPoiNT’s capabilities as a terrestrial, GPS-free network capable of powering critical national infrastructure in the event of GPS failure.

During a simulated 72-hour GPS outage, the TerraPoiNT service was able to deliver a timing accuracy better than 50 nanosecond in urban and semi-urban environments, successfully meeting timing requirements for various applications including 5G networks, the synchronization of the power grid, and more. In addition, TerraPoiNT provided precise timing and redundancy utilizing two alternate absolute timing sources – atomic clock (Cesium/Rb) and LEO satellite (Satelles).
“GPS is critical infrastructure, but it has its limitations,” said Ganesh Pattabiraman, co-founder and CEO of NextNav. “In working with DHS S&T, we’ve validated that TerraPoiNT can serve as an important backup to GPS and ensure the resilience and continuity of our nation’s most critical systems, including next-generation telecommunications networks, financial services, and power grids.”
The successful trial builds on recent evaluations of TerraPoiNT conducted by independent bodies. Earlier this year, the Department of Transportation (DOT) evaluated 11 alternate PNT solutions, in which each was rigorously tested across applications and scenarios. As a result of the evaluation, the DOT named TerraPoiNT the best and only performing solution across all PNT categories.
